I’ve always wondered if there is a way to stimulate a brain so that you could replay a memory so vividly that it practically feels like you are there reliving it again, like the way you might experience a dream but with more clarity, almost like a form of time travel. I remember reading about some experiment in a psychology class where an old woman’s brain was probed and she was able to hear her highschool graduation sonata clearly as if it was being played in the room. There must be a way, there’s so many memories I’d like to revisit firsthand, and people I’d like to see again that are no longer with us.

You can achieve this clarity in a lucid dream... how accurate the memories relived would be, is another matter

It's still very sci-fi now, but I would bet a fiver that in my life time-ish or 2 we will have bidirectional brain computer interface.

Take some ketamine :) ... I'm stating this as someone with first hand experience, so it may seem hand wavy and "made up": memories are visual and those visuals directly trigger your nervous system which then responds and often impacts the visual memory replay (often cutting it off or moving to something else). Your nervous system is also constantly telling your visual system what to "lookup". Ketamine dissociates the nervous system from visual memory so you can sort of play the memory through like a spectator. I think this is why it is so effective at treating things like PTSD -- the memories are often so frightening or triggering to the nervous system that they cannot be replayed, understood and integrated... but with Ketamine cutting off the nervous system they can be understood without a panic attack or heart rate shooting through the roof.
